Remove all references to sevenbridges tags

See merge request eosc/prefactor3-cwl!59

RabixComposer, which uses the `sevenbridges` namespace and `sbg` tags, cannot
handle CWL version 1.2 files. Removed all references to the namespace and tags.

Bump CWL Version to v1.2

See merge request eosc/prefactor3-cwl!57

CWL v1.2 is more explicit about the way that strings in embedded code that contain a dollar sign ($) must be escaped. See https://www.commonwl.org/v1.2/Workflow.html#String_interpolation. It turned out that a few workflow steps contained inline Bash code with improperly escaped variables references. This has been fixed.

Let inline bash scripts exit on error

See merge request eosc/prefactor3-cwl!56

Most of the inline bash scripts in the CWL files *ignore* errors, which is undesirable. This fix adds a `set -e` to all the inline scripts that did not have one yet. Note that adding a `-e` to the `#!/bin/bash` does *not* work, because the script is not invoked as an executable but as `bash <script-file>`.

Give inline scripts sensible names

See merge request eosc/prefactor3-cwl!55

Some of the inline scripts (bash or python) have names like "script.py",
which is not very helpful for debugging. Renamed the scripts for those
workflows that contained either script.py or script.sh.
